It seems for most varieties that pollen is usually or always infertile. Was wondering if this is because he beards are somehow mutations of something involved in anther/pollen development.. or some other biochemical cause... or perhaps historical genetic constraints.
Char said:In botany the term "beard" means a group of hairs or an awn and is botanically incorrect when describing characteristics found in daylilies. Use of the term "beard" in relation to daylilies has been rejected by the American Daylily Society since 2008.
NGA promotes and encourages the use of proper botanical and horticultural terminology. In the fall of 2010, the American Daylily Society approved and recognized Sculpted for registration as a form of daylilies with 3 distinctive form groups, pleated, relief and cristate.
To avoid further problems in the NGA Daylily Forum I'm asking everyone to please use the officially approved term, cristate, when referring to this form of sculpted daylilies. (Text beyond this post will be edited to the correct terminology.)
That said, while the Michael's Sword line is well known for it's infertile pollen issues the vast majority of known cristate forms, dip and tet, are both pod and pollen fertile.
Outcrossing should help with your pollen fertility issue. I would suggest adding other dip cristates to your crosses and not backcrossing into the MS line.
It's not fool proof. Sculpted in Vermont could be relatively pod fertile, but the sellers may just want to hold on to them for themselves, but you can learn a lot seeing what they are selling.
